Nuclear collective tunneling transitions between Hartree states deformed in quadrupole symmetry
M. Maruyama, T. Kohmura, Y. Hashimoto
In a nucleus which has two Hartree states deformed in quadrupole symmetry, i.e., prolate state and oblate state, the nuclear residual interaction derived in the present theory beyo…
Enhancement of Critical Slowing Down in Chiral Phase Transition -- Langevin Dynamics Approach --
T. Koide, M. Maruyama
We derive the linear Langevin equation that describes the behavior of the fluctuations of the order parameter of the chiral phase transition above the critical temperature by apply…
Linear Langevin Equation of Critical Fluctuation in Chiral Phase Transition
T. Koide, M. Maruyama
We derive the linear Langevin equation that describes the behavior of critical fluctuation above the critical temperature of the chiral phase transition in the Nambu-Jona-Lasinio m…
Projection Operator Approach to Langevin Equations in Theory
T. Koide, M. Maruyama, F. Takagi
We apply the projection operator method (POM) to theory and derive both quantum and semiclassical equations of motion for the soft modes. These equations have no time-convolu…
Current quark mass effects on chiral phase transition of QCD in the improved ladder approximation
O. Kiriyama, M. Maruyama, F. Takagi
Current quark mass effects on the chiral phase transition of QCD is studied in the improved ladder approximation. An infrared behavior of the gluon propagator is modified in terms…
A New Expansion of the Heisenberg Equation of Motion with Projection Operator
T. Koide, M. Maruyama
We derive a new expansion of the Heisenberg equation of motion based on the projection operator method proposed by Shibata, Hashitsume and Shingū. In their projection operator meth…
